He is right to a certain extent about Kickstarter, but Pay Pal is not the answer either Just ask Crate about their experience with Pay Pal and not being able to access their money.

There is a reason that you don't see pay pal donations as an option on the kickstarter page until after it is successful (besides the obvious one of diverting the funds and preventing a successful KS) is that pay pal might not release the funds to you as happened with Crate.

Though 10% is a lot cheaper then the 30% for steam early access, the part that sucks as an indi is everyone else has their hand in your pocket, but then again that is how business works in the real world.
